General Description
Minimum standby power is drawn by this device when
CE is at a high level, independent of the other input
levels.
Data retention is guaranteed at a power supply voltage
as low as 2.0V.
The A625308A is a low operating current 262,144-bit
static random access memory organized as 32,768
words by 8 bits and operates on a voltage from 4.5V to
5.5V.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.

tAS is measured from the address valid to the beginning of Write.
A Write occurs during the overlap (tWP) of a low CE and a low WE .
tWR is measured form the earliest of CE or WE going high to the end of the Write cycle.
If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs
remain in a high impedance state.
5. tCW is measured from the later of CE going low to the end of Write.
6. OE level is high or low.
7. Transition is measured ±500mV from steady. This parameter is sampled and not 100% tested.
